Whenever I get swimmer's ear (it is almost always from the shower) I use a drop of rubbing alcohol on a cotton swab in the ear. It always clears right up. The first time I ever got it, it was the first time I ever got an ear ache. I figured I could fight my way through it.... oh it was hideous. And it was right when my grandmother died too... i was popping tylenol by the handful! horrible!!
